Power Relays, Over 2 Amps

7-1617787-3 is a type of power relay, having current capacity over 2 amps. This type of power relay is designed to control various electrical circuits or components. It is usually used in automotive applications, where it can control the ignition, emission and fuel injection systems.

Applications

The 7-1617787-3 power relay is mainly used in automotive applications such as engine control, ignition control, fuel injection, and emission control. It is also used in heavy-duty industrial applications, as well as for residential applications, such as controlling appliances.

The 7-1617787-3 power relay offers the following advantages when used in automotive applications:

• It is compact and lightweight.
• It is reliable and durable.
• It is resistant to corrosion, vibration, and shock.
• It is low-resistance and has low contact resistance.
• It has a high switching speed and is capable of carrying high loads.

In heavy-duty industrial applications, the 7-1617787-3 power relay allows the effective and efficient control of induction motors, contactors, pumps, and other motor-driven equipment with high starting and operating currents.

Working Principle

The 7-1617787-3 power relay operates on the principle of a solenoid current. When activated, a solenoid current flows through a coil in the center of the relay. This creates a magnetic field which is used to operate the contacts on the relay. The contacts are used to control the flow of current to other components. In this way, the relay is used to control the operation of other components, allowing the user to control various aspects of a circuit or system.

The 7-1617787-3 power relay is operated by sending a signal to the control circuit. This signal can be in the form of direct electricity or an external signal, such as a switch. When the relay receives this signal, it sets up a corresponding current inside the coil. This current will produce a magnetic field that will trigger the contacts, which will in turn switch on or off other systems.

The 7-1617787-3 power relay is also used on control systems to act as a safety device, protecting the circuit from excessive current or voltage. By activating the relay, it will trip the circuit breaker and eliminate the risk of potential damage.

Conclusion

The 7-1617787-3 power relay is a versatile and reliable device, enabling the control of a variety of electrical circuits and systems. It can be used in automotive systems, heavy-duty industrial systems, and for residential applications. The relay works by sending a signal to the coil, which creates a magnetic field that will trigger the contacts to switch on or off. Finally, the relay is also used as a protective device, tripping the circuit breaker when excessive current or voltage is detected.
